The aminotransferral alanine test, also called ALT or TGP, is a blood test that helps identify liver damage and disease due to the high presence of the aminotransfer enzyme alanine, also called glutamic pyruvic transaminase, in the blood, which is normally between 7 and 56 U/L of blood.
The pyruvic enzyme transaminase is present within liver cells and therefore when there is damage to that organ, caused by a virus or toxic substances, for example, it is common for the enzyme to be released into the bloodstream, causing its blood tests to increase, which may mean:
- Although it is a very specific marker of liver damage.
- This enzyme can also be found in the muscles and heart in smaller amounts.
- And an increase in the concentration of this enzyme in the blood can be observed after intense physical exercises.
- For example.
Therefore, to evaluate function and identify liver damage, your doctor may request the measurement of other enzymes, such as lactate dehydrogenase (LDH) and AST or TGO. Learn more about the AST exam.
In cases where the pyruvic transaminase test is of high value, it is recommended to consult a hepatologist to evaluate the person’s medical history and identify what may be causing the liver change. Your doctor may also order more specific tests such as hepatitis tests or a liver biopsy to confirm the diagnostic hypothesis.
In addition, in case of elevated ALT, it is also advisable to make a diet suitable for the liver, low in fat and preferring cooked foods. Learn how to follow a diet for your liver.
The aminotransferralsa alanine test is used to detect liver damage and may therefore be recommended for people who have:
However, ALT levels can already be high even when the patient has no symptoms, which is an excellent tool for early diagnosis of liver problems. For example, the ALT test may also be done if there is a history of exposure to hepatitis virus, excessive alcohol consumption, or the presence of diabetes.
